michelle...I don't find those arguments sufficient to indicate that the "great multitude" of v. 6 is a separate from the "great multitude in heaven" of v. 1. The command to praise God in v. 5 does not imply that God's servants "both great and small" had not previously praised him, for this is what is described in v. 1. Rather, it signals a resumption of their praise following the intervening actions in v. 4 of the 24 elders. Indeed, the phrase "great multitude" is used to describe a "roar" (phónén) of praise which has the "roar" of v. 1 as its antecedent, which is again described as a roar of a "great multitude". Second, there is no reason why the passage should say that the roar is the third such statement of praise, for this is self-evident from the context. Third, I'm not sure what the timing of the wedding supper in v. 7-9 has to do with where the roar is coming from in v. 1 and 6; previous visions placed such roars and a "great multitude" itself in heaven, e.g. before the "throne" (Revelation 14:2, 7:9), and the bride does not come to earth until 21:2, after the eschatological judgment and the passing away of the "first earth" (21:1), so it is hardly self-evident that the bride is on earth in ch. 19. Moreover, the description of the bride, of those in New Jerusalem in 21:2-4 is precisely that of the "great multitude" of 7:14-17 who were earlier in the "temple" in heaven (cf. 11:19, 14:17, 15:5 which locate the "temple" in heaven), and it is there that they are united with the Lamb; later in ch. 21, after the passing away of the heavens and earth, do the Lamb and his bride come down together to a new, different earth. Finally, the language used to describe this "roar" in 19:6, that it is "like the roar of rushing waters and like loud peals of thunder", is exactly that of "a sound from heaven like the roar of rushing waters and like a loud peal of thunder" in Revelation 14:2. Although interpretation of the visions in Revelation can never be certain because of their symbolic and sometimes vague character, I don't see sufficient reason to assume a radical discontiunity between the "roar of a great multitude" in 19:1 and the "roar of a great multitude" five verses later...
